Ohh, wait, I have an even better idea. Get your self some sharks with lasers on their heads. When the sharks breath, they'll out gas the CO2 and they heat it up with laser to make it rise into your upside down carboy overhead. Of course, you'll have to fashion a one-way valve that with a CO2/O2 barrier membrane that only allows CO2 to pass through.
Whenever I see threads start to head in these types of directions ... it' reminds me of Dr. Evil from Austin Powers (or old Batman shows). Extremely complicated, dangerous and, frankly, idiotic schemes to do something that can be accomplished with a very simple act.
I've never purged my carboys before racking and have never had oxidized beer ... and I'm usually not even that gentle when racking my beer.

My emphasis: Use unwise in my opinion instead.
